• Designed and shipped a stateless overlay package manager for read-only RHEL Linux dev images, bind-mounting unpacked RPM content into a writable stateless partition to enable install/update/remove across 4 internal OS products
• Cut developer package refresh from >60 minutes for full VM reimages to <1 minute per RPM install (95%+ reduction); supported bulk installs and safe updates via state manifests and atomic rollback
• Hardened overlays with SHA-256 integrity checks, SELinux/MAC relabeling, and DAC/permission preservation; built a test suite to validate contexts, placements, and system file constraints (>60k files validated/test)
• Surveyed 10+ open-source servers against GRC and FIPS requirements, constrained-device footprint, and community supply-chain risk, ruling out heavyweight stacks and single-maintainer projects
• Configured and packet-traced HTTP/3 and TLS 1.3 stacks (tcpdump, traceroute, netstat) to verify real-world behavior; narrowed recommendations to Nginx, Jetty, and OpenLiteSpeed with hardened baselines
• Performed in-depth analysis of Linux USB enumeration, driver binding, interface classes, and common attack vectors (BadUSB, rogue HID, keystroke injection), mapping risk across udev, USBGuard, and device-authorization paths
• Developed advanced real-time auditing and correlation tooling that aggregates udev + USBGuard telemetry, producing concise security summaries and actionable logs for system developers

• Led a 5-member team building control systems for a 6-DOF robotic arm inspired by the Modern Robotics UR3 for presentation at UIUC's Engineering Open House event
• Developed Arduino Mega control framework for stepper/encoder integration and closed-loop actuation
• Implemented serial streaming between Python motion planning and Arduino firmware

• Built a high-throughput Amazon scraper to extract product and price data via concurrent requests with intelligent caching and session management
• Leveraged asyncio and aiohttp for concurrent web requests with BeautifulSoup parsing
• Modular design supports background or cron execution for automated price monitoring

• Implemented Google's PageRank algorithm using both sampling and power-iteration convergence methods on crawled web graphs
• Built HTML crawler and random-surfer transition model with damping factor

• Designed a full-stack social media web application using Django framework with Bootstrap frontend and SQLite database
• Integrated account/security management, posting, liking, commenting, and interactive features
• Applied Model-View-Controller architecture for maintainability and scalability
